Domestic garbage comprehensive treatment system and process

Abstract

The invention relates to the technical field of garbage disposal, in particular to a domestic garbage comprehensive treatment system and process. The system comprises a material bin used for containing domestic garbage, a comprehensive sorting device, a waste plastic disintegrating and oil refining device, a combustible gasification device and a high temperature and high pressure hydrolyzing device, wherein the domestic garbage is dewatered in the material bin to form solid garbage and leachate; the comprehensive sorting device is used for sorting the obtained solid garbage, and the solid garbage is classified into waste plastic, waste metal, combustible, inorganic matter and kitchen garbage in the comprehensive sorting device; the combustible gasification device is used for performing combustion treatment on the combustible; and the high temperature and high pressure hydrolyzing device is used for hydrolyzing the leachate and the kitchen garbage. By means of the system and process, reduction and resourceful treatment of the domestic garbage can be achieved, recycling and cyclic utilization of energy are achieved in the treatment process, and no secondary pollution is generated in the production process.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a domestic garbage comprehensive treatment system and process. Background technique [0002] The domestic waste treatment in the prior art is mainly landfill, composting and incineration. Among them, the landfill treatment needs to occupy a large amount of land. At the same time, the harmful components in the waste will also cause serious pollution to the atmosphere, soil and water sources, not only destroying the ecological environment, It also seriously endangers human health; composting requires sorting and classification of garbage, requiring high organic content of garbage, and composting cannot be reduced, and still needs to occupy a large amount of land; the essence of incineration is to put organic garbage at high temperature and supply Under the condition of sufficient oxygen, it will be oxidized into inert gaseous substances and inorganic non-combustible subst...
